Step 1: Draw a square with three vertices on each side (as shown in Figure 5); Step 2: Connect and extend the handover. ...
[How to draw a similar diagram] Methods and steps of drawing a similar diagram
The enlargement and reduction of a graph are usually drawn with the idea of potential transformation, and the position of the potential center can be at the vertex, edge, inside and outside of the graph. Taking a senior high school entrance examination as an example, this paper introduces several common drawing methods for students' reference. As shown in figure 1, the quadrilateral ABCD is known and can be enlarged with a ruler. ......
Graph Similarity Analysis of the First Volume of Mathematics in Grade 9 1.4 How to enlarge and reduce the graph material Qingdao Edition (202 1-2 ...
Enlarging or reducing a graph is actually drawing a graph like a graph. So how can we draw a graph like a graph? Let's take a test as an example to illustrate. For example, as shown in figure 1, in an 8×8 grid, the vertices of each small square are called grid points, and the vertices of △OAB are all on the grid points. Please draw in the grid. ......

The enlargement and reduction of graphics are usually drawn with the idea of similarity transformation, and the position of similarity center can be at the vertex, edge, inside and outside of the graphics. Taking a middle school exam as an example, this paper introduces several common drawing methods for students' reference. (Jinzhou) As shown in figure 1, we already know the quadrilateral ABCD, which can be enlarged with a ruler to make the graphics correspond before and after enlargement. ......
Concept and drawing method of potential diagram
It seems that a graph can be enlarged or reduced. Potential transformation can change a figure [c] A, enlarge or reduce B, reduce C, enlarge and reduce, and become a figure D with the same size as the original figure. Zoom in, for example, as shown in the figure below. To zoom in △ABC to twice its original size, we can arbitrarily take a point O outside the triangle and connect OA, OB and OC. ......
